Figure 8. Activation maps and temporal patterns of CBV during EM. A, Location of the first stimulation site (dCN, red arrow) on a sagittal view. B, Activation maps during dCN EM overlaid on the D99 atlas with ROIs outlined and labeled (red circles). C, Location of the second stimulation site (vCN, red arrow) on a sagittal view. D, Activation maps during vCN EM overlaid on the D99 atlas with ROIs outlined and labeled (red circles). E, Location of the third stimulation site (NA, red arrow) on a sagittal view. F, Activation maps during NA EM overlaid on the D99 atlas with ROIs outlined and labeled (red circles). G, 3D rendering of the D99 atlas (top) with two ROIs colored (orange, dorsal striatum; green, amygdala). Seven coronal sections are also shown (bottom; yellow lines from top). On sections 1, 2, and 3, purple dots and black arrows mark the dCN, vCN, and NA stimulation sites, respectively. H, Time course of percent signal change (colored lines) measured in the dorsal striatum during EM in the dCN (top) and amygdala during EM in the NA (bottom). Gray bars indicate 30-s stimulation periods and white bars indicate 30 s no stimulation periods (all 13 blocks are shown). To facilitate comparisons, the time courses are plotted with the same ordinate range. This results in some clipping in the top trace. dCN, dorsal caudate nucleus; vCN, ventral caudate nucleus; NA, nucleus accumbens; F2, agranular frontal area F2; F7, agranular frontal area F7; 12o, orbital prefrontal area; 46v, ventro-lateral prefrontal area; 10mc, medial prefrontal area; Iai, intermediate agranular insula area; MD, mediodorsal thalamus; VA, ventral anterior thalamus.
